The supervisor monitors the supply voltage for undervoltage conditions. During power up, when the supply voltage, VCC, attains a value approaching 1 V, the RESET output becomes active (low) to prevent undefined operation. If the supply voltage drops below threshold voltage level (VIT−), the RESET output goes to the active (low) level until the supply undervoltage fault condition is eliminated.
